DAVIE, Fla. (AP) — Florida wildlife officials say the lake where a 47-year-old woman was found dead from an apparent alligator attack has been the subject of multiple reports of gator activity.

Florida Fish and Wildlife spokesman Robert Klepper told the Palm Beach Post the agency has received 11 calls about alligator activity in the Silver Lake Rotary Nature Park area since 2005. Eight permits had been issued for alligator removals since 2005, but none were removed before Friday.

The most recent complaint came from a park ranger on March 26. It was about a 7-foot (2-meter) that was a threat to pets and people.

Shizuka Matsuki's body was found Friday, hours after authorities believe she was bitten by a 12-foot (3 meter) alligator while she walked her dogs at a park in Davie.
